WASHINGTON — The college basketball season is winding down, which means March Madness is upon us.

The annual men's and women's National Collegiate Athletic Association tournaments are among the most closely watched sporting events in the U.S.

No matter how much you know about college basketball — if you’re looking to follow the fun, make your own bracket, or even just understand what all the fuss is about — here are some key things to know.

What is March Madness?

It's the basketball world's term to reference the upsets, chaos, remarkable plays and historic moments that are sure to happen in postseason tournaments.

It all starts with teams playing a tournament against the other schools in their conference, which is the division that a school competes in during the regular season. One slip up there and a team could find itself “on the bubble,” or at risk of missing the ensuing NCAA Tournament.

And it ends with the ultimate prize: a school being crowned the champion as “ One Shining Moment ” is played over the airwaves.

The first NCAA Tournament in 1939 consisted only of eight men’s teams. Today, it’s a 68-team bracket that includes multiple single-elimination rounds.

The women’s tournament was formally added to the NCAA championship program in 1981, following the same format as the men’s. Typically, both championship games are scheduled for the same weekend in different cities.

The teams are selected, seeded and placed in a bracket by an NCAA committee made up of 12 members. The brackets are broken up into four regions: Midwest, East, South and West.

The goal of the committee is to create a bracket that’s equally competitive in each region.

The bracket formation process takes place the Sunday before the tournament begins, known as Selection Sunday.

Why is it called March Madness?

The term “March Madness” was first used by Henry V. Porter, a high school official in Illinois, in 1939. But the term wasn't officially used in reference to college basketball until 1982, when CBS broadcaster Brent Musburger used it during that year’s coverage.

Most of the tournament rounds have adopted their own names as well. There’s the First Four, Sweet 16, the Elite Eight, and of course, the Final Four.

Why do I hear so much about March Madness brackets?

Every year, millions of people fill out their own brackets in hopes of correctly guessing who will win each round. It’s a nationwide phenomenon that takes over offices, families and friend groups, with spectators and sports bettors competing to see who will have the most accurate bracket.

A huge reason why March Madness is so popular is its unpredictability. Lower-seeded teams regularly beat the higher-seeded ones, throwing brackets and predictions completely out of the window.

How is the bracket created?

Thirty-one of the 68 teams automatically qualify to play in the NCAA Tournament because they won their respective conference tournaments. The remaining 37 teams are chosen by that 12-person committee mentioned earlier.

Next, the committee will seed all of the teams. It determines seeding by wins, losses, strength of schedule and other metrics.

The teams are seeded 1-16 within each of the four regions. The top-seeded team will play the bottom-seeded team, and so on.

In 2011, when the tournament expanded from 64 to 68 teams, it also introduced the First Four round. That pits the four lowest-seeded automatic qualifiers and the four lowest-seeded at-large teams against each other. The winners enter the traditional bracket.

What if I fill out a perfect bracket?

Well, you’d be the first.

The odds of doing so are pretty absurd. The closest anyone has ever gotten on the men's side was an Ohio man in 2019 who predicted the entire tournament into the Sweet 16.

If you do happen to make a perfect bracket, there could be more in it for you than just bragging rights.

Perfect bracket pickers have been offered as much as $1 billion. That's the figure Warren Buffett offered to his Berkshire Hathaway employees in 2014 if any of them picked it perfect.

How can I watch the NCAA tournament?

Every game of the men’s and women’s tournaments will be broadcast live. The men’s will air on CBS, TBS, TNT or TruTV and their digital platforms, including Paramount+. CBS will handle the Final Four and national title game. The women’s will air on ESPN’s networks and streaming services with select games on ABC.

Selection Sunday is on March 16, the Sunday before the First Four, beginning at 6 p.m. ET.

PORTLAND, Ore. — On Friday, dozens attended a rally in downtown Portland, organized by Jewish Voice for Peace, where demonstrators called for a ceasefire in Gaza as well as the expansion of humanitarian aid. 

As part of this protest, the group called on Sen. Jeff Merkley to lead an emergency delegation to the Rafah border to demand aid trucks be let in and protected once inside.

"We just have to raise our voices. We cannot allow such a thing to continue to happen," said Jena Kain. "I feel like it's a moral imperative for us to stand up during this time."

"It's been incredibly frustrating to see how little progress has been made over the course of the past two years," said Anthony Bencivengo, "A ceasefire is so basic and isn't even the same thing as justice. It's just a halt to the slaughter. But that's still what we're pushing for right now."

As frustrations fuel protests in Portland, Oregon lawmakers also voiced their support of expanded humanitarian aid this week, amid reports of extreme hunger and starvation in Gaza. 

On Friday, Congresswoman Maxine Dexter joined other congressional doctors in sending a letter to President Donald Trump urging the administration to take action, highlighting "the extreme hunger, mass displacement, and near-collapse of Gaza’s health care system."

Earlier in the week, ahead of a Senate vote on a resolution that would have blocked U.S. weapon sales to Israel — a proposal that ultimately failed — Merkley released a video statement that said, in part, "People are starving in Gaza because the Netanyahu government continues to violate international humanitarian law by using food—more precisely the denial of food — as a weapon of war against civilians living in Gaza. We have a profound moral responsibility to end this collective punishment of innocent civilians."

The Israeli government has said there is no starvation in Gaza. Humanitarian groups, including Mercy Corps, have disputed this claim. 

"This is not a logistics problem. It's not a coordination problem. This is a political problem because we have unfortunately seen Israel blocking aid and commercial goods to only a tiny trickle getting into Gaza over the last several months," said Katy Crosby with the organization. "We really are at the point where we are nearing famine and mass starvation. We need to see greater political pressure to alleviate this catastrophe."
